Summary: newly ordered Tesla Model S60D with glass roof is exactly same price as 75D, car haven't been delivered, but Tesla is asking for a $500 modification fee. It is not like I have already been driving my car for few days!!! At this point, I feel this urge to search for other people's help, voice, and ideas since Im so helpless. How should I start? So I placed an order with Tesla from their Pasadena show room on the 30th of March, 2017, for my Model S 60D . My salesperson was very helpful and strongly recommended me to place the order before the end of march, he told me that Tesla is going to discontinue Model S 60 and 60D after the last day of march, so it is a huge deal if I can order before that. But after I placed the order in just 2 weeks, Tesla already lowered the 75D price to exactly what I am paying for the 60D(in 75D the glass roof is included in the price, which I did add glass roof with my 60D, so the price is exactly the same), which at that point, Tesla has not even begin to make my car yet! But this happen, non of Tesla associates told me anything about this huge news, which I found out later when I was browsing the Tesla website. So I contact my salesperson, he explained to me if I want to upgrade to 75D, I need pay $500 fee for the difference, then I told him I did some calculation myself, so what I am paying for the 60D is exactly same price as the 75D, and I haven't got my car, I don't feel like I should be paying for this fee for nothing. He told me to contact his manager, then I went on playing a game called "finding a person who can really give me an answer". I keep having this feeling that they are just dragging time, so later on they could tell me that" I am so sorry, your car is already been made, so there's nothing we can do about it" excuses like this. Now this whole thing just doesn't seem to make any logically sense to me, I haven't got my car, Tesla haven't begin to make my car, what I am paying for is already exact the 75D!!! why am I paying $500 extra for nothing? what is there to modify? This is suppose to be a very exciting experience for a newly Tesla future owner, I was so exciting for my new order, but now this whole thing came up, I try to find someone I can talk to, I don't seem to get any help from people who work in Tesla, I talked to 2 different sales in their show room, (because I can't find my own sales, so I went to the store twice see if I can get luck to meet him there), 2 different representative on their costumer service phone, I try to contact my delivery specialist, I left voice mail for their show room manager as well. I really don't know how come it is so hard to find someone who can help me with a such big company like Tesla! It seems like after I paid my $2500 deposit, no one care about me anymore, is this how Tesla treat their customer? Wow, what a shopping experience! if anyone knows any useful information that can share with me, please do help! thank you all.
